Heh, yea. That's why, even though I use Haxe, I don't use it for generating 
JS (unless I wanted to do a Flash-style HTML5/canvas thing).

Suggestion: Allow all D features even if it 
requires...inefficient-er...boilerplate, BUT then have a system similar to 
@safe/@trusted/@system (or maybe just a "pragma(SimpleJS)") so a developer 
can selectively turn on "Disallow any D features that would result in 
extra-inefficient JS output" at the module-level (and/or whatever other 
granularity @safe works on).
